Mains Power
Mains power is supplied via the standard IEC 3
-
pin connector on the rear panel. The mains circuit does incorporate filtering
circuits to ensure the feed is clean, and therefore the use of external mains filtering systems is unnecessary.
We recommend, for safety reasons, that connecting the mains should be left as the last step.
Switching on
Before switching the unit on, ensure the volume control is turned to its minimum level (fully anticlockwise). Your Sigsum
amplifier has a mains switch, which is hidden on the bottom of the unit, in the middle of the front panel. There will be a few
clicks from internal relays as the protection circuit is activated during the first few seconds. There is a single, blue LED on the
left of the unit (in the large ‘A’) that is illuminated whenever the unit is on.
